Great war, fighting.

Chaotic, orderly.

The vast filthy land has ushered in its second wave of battles.

But Romney and others did not.

As outsiders, although they were not welcomed into Panda Immortal Island, they were also heavily protected in the rear of the "Xianwu Army".

Following the Golden Armor Panda Legion and the Xianwu Legion, Panda Immortal Island sent elite troops in.

These troops are another group of high-ranking martial disciples of various factions.

With the entry of their own immortal masters, the various factions linked up with the Golden Armor Panda Legion, the backbone of the formation, and the Immortal Martial Legion of the front breaking formation, forming three attack formations: decapitation, main battle, and enemy breaking.

Because in the filthy land, all the Pandas could not quickly replenish their spiritual power.

Therefore, Panda Immortal Island has set up a logistics base camp near the Blood Forest, the residence of the "fairy".

Together with the volcano and the earth plain, the three logistics camps surrounded the line of the Blue Molten River and built a cutting opening.

The battlefield of the entire filthy land starts from this blue molten river, presenting the two battlefields of the east and the west.

After the North Volcano, the Middle Earth Plain, and the South Blood Forest.

The eastern and western battlefields have once again cut a filthy land.

It was at this time of strategic change that Romney and others were amicably "ordered" to live next to the "fairy".

Unable to participate in the war in person, Romney and others are also actively doing what they can.

Take Romney, for example.

After thinking that the Vajra Fly could help Panda Immortal Island, he began to try to improve the Vajra Fly in this filthy land with the help of the four daughters of Spring, Summer, Autumn and Winter, and Xi Luo.

The King Kong fly in the past was said to be a kind of Warcraft fusion product.

Now it is necessary to improve and adapt to the environment of the filthy land.

Then, it is necessary to continue to write on the point of integration.

With direction, Romney studied it carefully in the days that followed.

Starting from cultivation and reproduction, through feeding, injecting blue molten slurry, blood forest wood blocks, lead black soil sacs, and then secretly picking lotus flowers dripping from the tears of the "fairy", and finally trying to use those weird ghost corpses as materials.

Before and after, he killed the hundreds of vajra flies he was carrying.

As a result, it was a complete failure.

Cross-environment cultivation is too difficult, and Romney knows it.

But he thought that relying on his identity as the "core of plane luck", there would always be some places where his luck was bursting.

And the reality told him that even if he is favored, he does not succeed in a vacuum.

There is no detour to take.

Not discouraged, Romney used the remaining 200 vajra flies to conduct the 665th experiment.

In this experiment, Romney is going to use the blood of the Gattooth Ghost, the Blood Forest Wood Block, and the Blue Molten Slurry as nutrients for the petri dish.

Increase the lead demon bones, the spine of the tooth bone demon, and finally use the newly obtained six-legged giant's heart as the petri dish itself, and conduct the 666th experiment.

Digital Geely, Romney and others are looking forward to it.

Three months later.

"Damn!!"

Romney angrily smashed all the footage and sat down to the ground in annoyance.

"What's wrong?"

Grace heard the crackling sound of the device popping and hurried over.

"It's okay, my emotions are a little out of control."

Romney sighed, waved his hand, and told the crowd that he was fine.

"Spring, summer, autumn and winter, you clean up."

"You come with me, don't be bored here, never go out, where can you be in a good mood."

Grace turned his head sideways to signal Spring, Summer, Autumn and Winter to hurry up and clean up, and then strode over and pulled Romney up.

"I haven't made it yet."

Romney also wants to continue diving headlong into research.

"Let's go, take a break, maybe there will be some other inspiration!"

Grace knew that as soon as Romney engaged in scientific research, it was easy to concentrate.

Usually a prince, when he entered the laboratory, he was a pure scholar.

This change also made Grace always snicker at Romney more like a scholar than a prince when he took care of Romney.

Romney didn't argue either, he liked the title of scholar and magician.

If it weren't for him, perhaps he would have been immersed in the journey of exploring the mysteries and truths of the world for the rest of his life.

"Let's go, don't stay in the lab."

Romney was dragged out of the lab by Grace.

The onlookers were not surprised, and in the days after the start of the study of magic science, every few days, there would be a stiff pull.

"What's the problem this time?"

Grace led Romney to the edge of the eerie bloodforest.

"It's still an internal conflict in the genome, and this problem has not been solved."

"The genes of the King Kong fly itself have a very suitable degree of survival, and I want to add some of them, because the transmission conditions of the original beneficial genes continue to conflict with the transmission of new genes."

"There is also a conflict between the genes in the nucleus and the genes outside the nucleus, and the problem has always been stuck here."

Romney was a little irritable, but his words were clear, and he threw out all the key questions.

"Well, let's try something else."

"What kind of gene editing technology did you say before?"

Grace listened to Romney's words as if she didn't understand them, but she always remembered some of the terms Romney had come up with.

"The problem is, I won't."

"There's no basis for modern scientific research here, and the magic science at the biological level is all done by me using magic."

"If you want to change the nuclease and change the base, it's like rearranging the elements, where is it so ......"

"Wait...... Element rearrangement? ”

"I see!"

"I got it!!"

"Grace, I got it!!"

"Let's go, let's go, let's go to the lab!!"

Romney was still casually talking about the difficult points, but suddenly, as if a flash of inspiration, he jumped up with excitement and excitement.

Shaking Grace excitedly while jumping, happy to the end, he actually picked up Grace directly, and after a few teleportations, he returned to the laboratory.

The "fairy" who peeked at the romantic scene here from a distance was sad, and once again remembered the good days of the past, and the lotus was born on the ground.

The sun is slanting in the west, and the winds of the world colliding slowly arise.

The environment in the filthy land is changing day by day.

Romney's experiment, after that day's burst of inspiration, made a breakthrough.

Through the control of the magical elements, Romney succeeded in realigning the conflicting genes.

In more than 100 days of gene editing, the fusion of the original gene fragments of the Vajra fly and many gene fragments in the Filthy Land was completed.

The newly born Vajra fly is no longer called Vajra fly.

Romney gave him a new name.

"Clean Fly"

The so-called clean fly became famous after the opposite of the filthy land.

Since you have to deal with filth, you have to be clean.

Therefore, Romney tried to reject all the names of the victory fly, the certain fly, the super fly, the invincible fly, the cleaning fly, the cleaning fly, and so on.

and he ordered the flies to be clean.

With the initial foundation, the subsequent cultivation will become more and more smooth.

What started out as a pair of cleansing flies was spawned by Romney's bloody investment in three lead demon bones.

In half a month, more than 200 million were bred.

Cultivated at room temperature, the reproduction rate of one generation is one day; second-generation quantitative fission, which took five days; Three generations of fission are huge, and it takes nine days.

A generation of clean flies can lay 400 eggs.

All of them hatch into 400 clean flies, and each generation can basically have more than 180 pairs.

The second generation is 72,000 clean flies, and 35,600 second-generation couples are paired to produce 14,240,000 clean flies.

Three generations are 7,114,823 couples of three generations, producing 284.5 million clean flies.

In three generations, a total of 284.5 million clean flies were baked.

Romney has tested that arming the user with 500 units can achieve the protective effect of the Vajra Fly.

A total of 569,000 units of the Clean Flies were immediately available for use and put into the battlefield to arm the Golden Armor Panda, who was at the forefront of the campaign.

But no one believes in new things.

The cleansing fly, which targets the demons of the Filthy Lands, is no exception.

Nor could Romney find any high-level officials on Pandaxian Island to directly use the flies on a large scale.

But fortunately, Pan Yilong was promoted, and with the help of Da Mao and Xiao Tao and others.

Romney used the 3,000 gold-armored Panda led by Pan Yilong and the Qingniu Yimai as the initial pilot, and put the armed unit of the Clean Fly into the battlefield named "Immortal Demon Battlefield".
